CNS Irradiation Effects on Puberty and Growth

Pediatric Neurology Briefs, 1996
The relation between age at irradiation, sex, and age at puberty onset was determined in 36 children treated with high-dose irradiation for tumors anatomically distant from the hypothalamic-pituitary region at the New York University Medical Center, St ...

Radiation-induced gliomas represent H3-/IDH-wild type pediatric gliomas with recurrent PDGFRA amplification and loss of CDKN2A/B

Nature Communications, 2021
Radiation-induced gliomas (RIGs) have been reported in patients after treatment with cranial irradiation for various primary malignancies but their origin are still unclear.

Dosimetric analysis of thyroid doses from total cranial irradiation

, 2007
The purpose was to estimate the radiation dose to the thyroid from total cranial irradiation with parallel opposed lateral fields of 1.25 MeV gamma rays of Co-60, to represent the current treatment modality, and with 6 MV photon beams derived from a ...

Neuropilin 1 and 2 control cranial gangliogenesis and axon guidance through neural crest cells [PDF]

, 2008
Neuropilin (NRP) receptors and their class 3 semaphorin (SEMA3) ligands play well-established roles in axon guidance, with loss of NRP1, NRP2, SEMA3A or SEMA3F causing defasciculation and errors in growth cone guidance of peripherally projecting nerves ...

Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

Advanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Cranial irradiation and early puberty

, 1994
Low doses of cranial irradiation (18-24 gray) employed in the management of acute lymphoblastic leukemia may cause early or precocious puberty, predominantly in girls.
